1) Electrical phenomenon 
the direct conversion of light into electricity
When light energy or emissions are converted into electricity.
(PV) Pertaining to the direct conversion of light into electricity. The word 'photovoltaic,' first used in about 1890, is a combination of the Greek word for light and the name of the physicist and electricity pioneer Allesandro Volta. So, 'photovoltaic' can be translated litera...
Generally speaking, a device incorporating a semiconductor that generates electricity when exposed to sunlight (or any other form of white light). The technology may be further sub-divided into crystalline, multi-crystalline, thin-film and concentrator variants.
Materials that convert light into electric current. 
the direct conversion of light into electricity
[adj] - producing a voltage when exposed to radiant energy (especially light)
photovoltaic (PV) 1. Employing the photoelectric effect; that is, the production of electric power from electromagnetic radiation. 2. Relating to, or designating devices that absorb solar energy and transform it directly into electricity. 3. Able to generate a current or voltage when exposed to visible light or other electromagnetic radiation.
Refers to the conversion of light into electricity.
